Pathogenesis: How Germs Made History by Jonathan Kennedy explores how pathogens have been the protagonists in many of the most important social, political and economic transformations in history - the demise of the great empires of Antiquity, the transformations of Christianity and Islam from small sects in Palestine and the Hijaz to world religions, the devastation wrought by European colonialism in the Americas and Africa, and the creation of the modern welfare state.

Dr Kennedy maintains that the modern world was shaped by the spread of disease, much more than by the actions of individual men and women.

He also issues a warning that pathogens are not done with us yet. “We’re living in a golden age for microbes. Population densities are increasing, people are moving more quickly around the world, the climate is changing. We’ve seen the emergence not just of Covid, but of HIV/Aids, Zika, Dengue fever, Sars and Ebola. It seems now that we won’t be able to conquer infectious diseases. Rather, by working together globally, we’re going to have to learn to deal with the new diseases that periodically arrive to threaten us.”

Dr Jonathan Kennedy is a sociologist, teaching Politics & Global Health at Queen Mary University of London.

This episode deals with the emergence of slavery in the Caribbean and mainland America, and explains that plantation workers brought over from West Africa were much less susceptible to malaria and yellow fever than European labourers. It also deals with the Revolutionary War in America and the failure of a Scottish company to set up a trading settlement in Panama.
